[Bug 1578742] [NEW] No sound on HTML Vidéos in Firefox

[PEIGNOT Kévin]

Public bug reported:

Hi,

I have a bug today with Firefox and Videos / sound : I have no sound
with HTML vidéos(or sounds). No problems with Flash ones. I tried to
restart without extensions, no problems. There's been a Firefox update
today, but bug appeared before the update.

If I go in the sound parameters, it seems to be something in
applications tab (Cubeutils line, sound isn't mute). I really don't know
what changed to bring this bug !
